Photoelectric goniometer

Abstract

The invention discloses a photoelectric goniometer. The photoelectric goniometer comprises a computer, a video acquisition system, a detection basis platform and a matching cable, wherein the computer has a PCI interface for mounting a video acquisition card and an interface capable of mounting an RS485-to-RS232 signal converter, the video acquisition system comprises the video acquisition card and a CCD camera, and the detection basis platform comprises a detected product disposing portion and an image data acquisition portion. The photoelectric goniometer can effectively solve problems of easy fatigability of a detector during alignment observation and relatively large subjective error, further improves work efficiency and is convenient for query and printing of historical data.

Description

technical field [0001] The invention belongs to the technical field of optical detection equipment, and relates to an instrument for detecting the angle error of the optical observation or aiming product of the Zhoushi series, in particular to a photoelectric goniometer used for the angle measurement accuracy detection of the Zhoushi sighting mirror direction. Background technique [0002] Generally, Zhoushi series optical observation or aiming products have detection requirements for the accuracy of direction angle measurement. In the detection instruments of the prior art, a turntable or a special angle detector is usually used for detection. This type of traditional optical-mechanical detector mainly The composition includes a front mirror, a reading microscope, and an angle mechanical dial. The former two are used for alignment, and the latter is used for angle indication. The usual method of use is to observe the cross center of the front mirror reticle with the human ey...

AI Technical Summary

Problems solved by technology

[0003] There are four deficiencies in the above-mentioned traditional detection method: one is to provide the front mirror reticle aligned with the reticle of the product under test and the angle mechanical reticle and the microscope for reading the rotation angle value to be set at one high and one at the same time. In a position with a low height and a large height difference, the operator must not only observe the alignment through the front mirror and microscope, but also manipulate the relevant mechanisms of the instrument during the detection process. mass production of products

The second is that the mechanical dial used to indicate the angle has extremely high technical requirements. Once it is deformed or damaged, it is extremely difficult to purchase and manufacture, and the entire instrument will be unusable, and the maintainability is poor, which will affect production.

The third is that the human eye is prone to visual fatigue due to repeated observation of the alignment and reading through the front mirror and microscope with a small exit pupil diameter, and the alignment is inconvenient, the error of the human eye is large, and there is a certain degree of randomness, which affects the measurement. Authenticity and credibility of results

The fourth is that the measured data can only be recorded by hand, and finally the maximum value is selected from a pile of data. It is inconvenient to save the detection data and trace back the history
